Must be. I had fun with it a little and put the extra I had on the Q-tip on a pop can and it was fun cause it turned all grey and kind of broken up like it was rusting almost.

As for copper though I haven't heard anyone say there was an issue with copper and gallium. If I am reading this:
http://link.springer.com/article/10.1134%2FS0036029508060049#page-1

and the wiki article right, Gallium simply soaks into the pores in metal much like solder does. With most metals this is harmful, but with the copper sounds like it didn't really show any signs of breaking down, it just fused into the copper without issue. Which if it doesn't degrade it should actually be a good thing since it will better transfer heat into the metal.

What kind of thermal paste are you using?
If its just mediocre stuff that might be the issue if you are landing around 70C.

Could be just a bad chip though. Since the Haswell chips have the voltage regulator on chip they run hotter and are more susceptible to defects. I also cannot see your screen shots well enough to see your temps though.

Also could be the cooler isn't functioning well. I've heard a lot of things can go wrong with the closed-loop coolers to greatly harm performance.

So first off those images are so tiny that I can't even see what the heck is going on. Just edit your post and tell us what is actually going on, such as "I am getting 70°C at full load at stock speeds and voltages"

Chances are, you just have a chip that runs hot. My own Haswell computer has this issue. These CPU's as well as Ivy Bridge are garbage for overclocking compared to their predecessors because at the end of the day, you are relying on Intel's thermal paste to get the heat to the heat spreader before you can even remove it with your own thermal compound and heatsink. Haswell, in fact, is actually worse than Ivy bridge. Less consistent, more prone to heat problems. Many people building brand new systems today are building Ivy bridge because they are more consistent than Haswell and don't have quite the heat issues that Haswell is known for.

My experience with my own 4670k is as follows:

--At stock speeds and voltages with the stock heat sink (even with AS5 in place of the stock thermal compound, I tried...) I was bouncing off the thermal throttle limit (105°C) under full load.
--The maximum overclock I've been able to achieve within reason is 4.4 Ghz. @ 1.27 V which lands me at 95°C under full load.

Also, the H100 isn't the end of the world. I doubt it's more than 10% better than my own air cooler (NH-D14).

TL,DR? Probably normal.

Well I got a good deal on the h100 so it was more worth compared to the price of a noctua... However I have read that about Haswell, I actually had a 3570k z77 build but my sabertooth crapped out on me. So i decided to get a combo from microcenter... I guess its just puzzling to me how one architecture that isnt that much different from its predecessor could behave so differently. I could understand if i was oc'd to say 4.2 or 4.4 but were talking stock 3.4 and with boost like 3.7 on load. With prime the other day my temps werent bad at all,granted my ambient was a lil better then. Today however running small for 20 minutes or so my package temps were hitting around 73c. Its been reseated but i did read that since the ihs on haswell is smaller than ivy that 1155 socket coolers dont get a proper fit sometimes as far as mating perfectly together. Again this could be less factual but who knows.

Yes, its hotter, but I dont think you should worry. Prime 95 puts the cpu under stresses which are unlikely to occur in real world processing. Also, 70C is moderately hot. You still have an overclocking headroom of about 15-20 degrees. You cant do anything if you got a hot chip, however, you can ensure these-
1. Check all the fans are spinning properly without any obstruction. Clean and replace if necessary. Ensure free airflow.
2. Check thermal paste between heat sink and CPU. It should not be too much or too less. It should be such that there is no air between the CPU and heat sink joint.
3. Ensure the heat sink is tightly secured in its position with all the screws up to the recommended tension level or clips positioned correctly and secured.

Like he mentioned above, Ivy Bridge is doing a lot better still. Haswell is hotter and too inconsistent. It does have a minor IPC boost of what I've read is only about an average 3% boost, but Ivy Bridge overclocks further and better. For example my i7-3770k is at 4.45Ghz without any voltage increase and sits around 73C at full load. Taking it further wouldn't be hard at all, but I don't see the point at the moment since it will beat any Haswell i7-4770 clocked 4.3Ghz or less.

If you already had an i5-3570k, you would of been better off to get a new motherboard and a better cooler and you would of had better performance.

If you plan to overclock like verma1891 said, you still have some headroom. You can look into deliding if you brave, cause that can really lower temps big time. Or maybe get some Liquid Metal Pro, it works really great if a little bit of a pain to spread at times. Its expensive but the $15 tube of it I had was enough to do my two 7850's, my CPU, my laptop's GPU and CPU, and still have at least half a tube left. Really not a bad idea.

after looking at reviews I think I will purchasing some PK-3 soon. It seems less conductive and less likely for issues removing water block. Galium and Aluminum isnt pretty so I could just imagine what it and copper would do over time... so I think Ill go with PK-3

it still shouldn't be too difficult. The stuff melts at like 30C. It literally melts in your hands so worst it could do is if its sticking, boot up the PC, run a heavy stress test on it so it heats up, then shut down and take it off cause it will melt. Or a hair dryer on low might get it off, but really shouldn't be so hard. I'm loving the stuff so far. Thats why I put it on everything not made of aluminum lol.
